PATENT SPECIFICATION
( 11) 1 586 977 ( 21) ( 62) ( 31) Application No 1337/80 ( 22) Filed 8 Jul 1977 Divided out of No 1586976 Convention Application No 7607602 ( 32) Filed 9 Jul 1976 in ( 33) Netherlands (NL) ( 44) Complete Specification Published 25 Mar 1981 ( 51) INT CL 3 F 16 C 35/04 ( 52) Index at Acceptance F 2 A 5 B 4 7 F D 16 ( 54) PROCESS OF PRODUCING A HOUSING FOR A Y-BEARING ( 71) We, SKF INDUSTRIAL TRADING AND DEVELOPMENT COMPANY B.V, a Company organised and existing under the laws of the Kingdom of the Netherlands, of P O Box 50, NIEUWEGEIN, the Netherlands, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the follow-
ing statement:-
This invention relates to a process of producing a housing for a Y-bearing and to the housing produced.
The invention provides a process of producing a housing for a Y-bearing comprising providing a plate having a central aperture, splitting the inner edge of the aperture part the way along the plane of the plate and then shaping the split inner edge to form a bearing surface.
The invention also includes a housing for a Y-bearing produced by the above process.
The aperture may be widened, at one side of the housing, at two diametrically opposed locations to the external diameter of the outer race ring of the Y-bearing to be housed.
Embodiments of the invention will now be described by way of example and with reference to the accompanying drawings, of which:Figure 1 is an axial section of a housing for a Y-bearing; Figure 2 is a view from the left of the housing shown in Figure 1; and Figure 3 is an axial section of half of another housing for a Y-bearing.
Figures 1 and 2 and Figure 3 are two embodiments of a housing for a Y-bearing.
A Y-bearing is basically a deep groove ball bearing having an outer race ring with a spherical outer surface which in combination with the appropriate housing can accommodate initial misalignment of the shaft The housing has been known to be made by either casting it of iron or aluminium, in which case the bearing surface has to be accurately machined, or by pressing it from steel which is subsequently galvanised.
A known pressed steel housing has been made in two parts.
The embodiment shown in Figures 1 and 2 comprises a steel plate 30 which provides a spherical bearing surface 31 for the outer race ring of a Y-bearing and a flange 32 The plate 30 has a circular aperture of which the inner edge has been split part the way along the plane of the plate and then shaped to form the bearing surface 31 The flange 32 has been formed after the inner edge of the aperture has been split, and has bore holes 33 At two diametrically opposed locations 34, the aperture, at one side of the housing, is widened to the external diameter of the outer race ring of the Y-bearing to be housed, so that the bearing can be located in the housing Such a housing is light and strong, since at the point of maximum loading, the bearing surface 31 is completely supported by undivided plate material The bearing surface is accurately formed and the housing able to withstand radial and axial loads The housing is suitable for mass production in a variety of shapes.
Figure 3 shows an embodiment in which the bearing surface 31 has an annular groove which can be used as a lubrication channel fed through drilled hole 36 The annular groove 35 can be formed by splitting the plate from the inner ege of the aperture further than is necessary for forming bearing surface 31 such that after bearing surface 31 has been formed the annular groove 35 is left.
The process of the invention of producing a housing 30 having a bearing surface 31 and a support means 32 in which the bearing surface is formed by splitting an arcuate edge of the plate before the support means 2 1 586 977 2 is formed eliminates complicated centring procedures and allows the production of housings in which the number of component parts is reduced.
The actual technique of splitting the edge of the plate is accomplished by known means.

Claims (4)

WHAT WE CLAIM IS:-
